"Application filed March 15,1523. Serial No. 625,264. 7 i 1 J To aZZwJzom it may concern I Be it known that I, Jozsnr Donron, a citizenof Hungary, residing at (ll-airsvilla in the county "of Belmont and State of Ohio, have invented certain new and-useful improvements in Rail Scarf- Joints, of which the following is a specification.

This invention relates to certain new and useful improvements in railjoints and particularly to a joint of the scarf type wherein the meeting ends of rails are cut away to provide overlapping end sections having in terloclring connections with devices associated therewith for holding the meeting rail ends in a locked condition.

V'Jith the above and otherobjects in view as the nature of the invention is better un dcrstood, the same consists of the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed.

In the drawing, wherein like reference characters designate corresponding parts throughout the several views,

Figure 1 is a side elevational view of the meeting ends of a rail scarf joint constructed in accordance with the present invention,

Figure 2 is a top plan view thereof showing the overlapping scarf ends of the meeting rails,

Figure 3 is a longitudinal horizontal sectional view taken on line III-III of Fig. 1 showing t is interlocking connection between the scarf portions of the meeting rail ends and the locking devices associated therewith,

Figure 4 is a perspective view of one of the rail ends,

Figure 5 is a perspective view of. one of.

the rail locking devices, and

Figure 6 1s a side elevational view of the cooperating rail locking device.

Referring more in detail to the acco1n-,

panying drawing, there is illustrated a scarf joint for rails, the meeting rail ends 1 being of like construction for cooperation with each other, the formation thereof being more clearly shown in Figs. 3 and 4.

Each rail end 1 has one side of the tread, web and base flange cut away to provide a scarf extension 2, the rail web being of increased cross-sectional area as at 3 at the inner end of the scarf extension 2, the contacting faces of the scarf extensions 2 being disposed at an angle to the longitudinal side edges of the rail sections 1 as shown in Fig. 2.

The web portionof the scarf extensionf2 provide a rib 8. A shoulder 9 is formed integral with the inner face of thescarfextension ,2 adjacent the forward end thereof and carries a forwardly offset block portion 10 defining a pocket 11 between said blockand the adjacent forward end of the scarf extension as clearly shown in Figs. 3 and 4.

In connecting the meeting rail ends, the scarf extensions 2 upon adjacent rail ends are disposed laterally of each other with the blocks 10 alined with the forward ends of the openings 4, movement of the rail ends in lateral directions toward each other projecting the shoulders 9 and blocks 10 through the adjacent openings 4, at which time axial movement of the rail ends toward each other will cause the ribs 8 upon the web portions 3 of the rail to be received in the pockets 11 between the blocks 10 and scarf extensions 2 as shown in Fig. 3, the openings 5 being then transversely alined.

To retain the meeting rail ends in a locked condition, an L-shaped bolt of the form best illustrated in Figs. 3 and 6 has the leg portion 12 thereof projected through the registering openings 5, one end of the leg carry ing the laterally extending arm 13 provided with a lug 14 upon theinner side thereof to be received in the space between the outer edge of the post leg 6 and the rear edge of the block 10. The free end of the leg 12 projects beyond the opposite side of the scarf joint and is provided with a notch 14 upon the lower side thereof that receives the pin 15 carried by the block 16 for retaining the L-shapedbolt in a locked position with respect to the scarf extension, he head 16 carrying a side lug 17 to be received inthe space between adjacent ends of the leg 6 and end wall of the block 10, the pin 15 being preferably formed of resilient material and having a finger notch 18 in the head 16 thereof to facilitate removal by displacing the lug 17 from said pocket.v

While there is herein shownand described the preferred embodiment of the present intions thereof, a shoulder and offset block carried by the innerface of the. scarf extension adjacent the forward end thereof to, be received in a, cooperating opening of the other scarf extension, and means, for locking the: interlocked scarf extensions;
